PV Branch Connectors FAQ
Product questions
Find answers about fit, wiring and product differences.
PV Branch Connectors
01Does adding branches increase the current in the shared connector?
Parallel branch currents combine at the shared path. Size that connection for the circuit design and the connector rating; do not use a single-string current alone.
02Does T or Y shape determine polarity?
No. The body shape describes the cable layout. Check the contact arrangement and polarity markings for the branch connector and its mating parts.
PV-T Series Rigid Branch Solar Connectors
PV-T Series Rigid Branch Solar Connectors
01How many branches do the PV-T models provide?
PV-T3 provides two branches; PV-T4 three; PV-T5 four; PV-T6 five; and PV-T7 six. Each has one common connection.
02Do all PV-T models have the same electrical rating?
No. Use the current and voltage values for the exact PV-T model in the comparison table. The common connection carries the combined branch current.
03How much space does a PV-T branch connector need?
Body width increases with the number of branches. Use the selected model drawing for its overall dimensions and leave space for the mating connectors and cable bends.
04When does the PV-T IP67 rating apply?
IP67 applies to the fully mated connection. Keep unused connections protected from water and dirt.

01How is PV-Y3 arranged?
PV-Y3 uses 2 branch connections and one common connection.
02Can PV-Y3 replace a complete combiner box?
It provides a parallel connection. It does not by itself replace the isolation, overcurrent protection or surge protection that a circuit may require.
03Does PV-Y3 have a fuse as standard?
Fuse and diode configurations are options. They are not included in every branch connector.
PV-Y4 3-Branch Solar Connector
PV-Y4 3-Branch Solar Connector
01How is PV-Y4 arranged?
PV-Y4 uses 3 branch connections and one common connection.
02Can PV-Y4 replace a complete combiner box?
It provides a parallel connection. It does not by itself replace the isolation, overcurrent protection or surge protection that a circuit may require.

PV-Y5 Multi-Y Solar Connector
PV-Y5 Multi-Y Solar Connector
01How is PV-Y5 arranged?
PV-Y5 uses a multi-Y arrangement. The exact outlet layout is selected with the connector configuration; the model name alone does not define the number of branches.
02Can PV-Y5 replace a complete combiner box?
It provides a parallel connection. It does not by itself replace the isolation, overcurrent protection or surge protection that a circuit may require.
03Does PV-Y5 have a fuse as standard?
